Probe into IP address and DHCP setting of router in multi-router environment

Here the LAN port management IP address of the router is called the gateway address of the router, the router that connects directly to the Internet is called the primary router, and the other routers are called from the router. Setting up routers in a multi-router environment personally, the following principles should be followed:

1. If the primary router entry address is 192.168.1.1, then the router is finally set to 192.168.x.1,2≤x≤254.

2. If the primary router lan port → Wired → from the WAN port of the router, then from the router can turn on the DHCP function, from the router to hang the computer from the router to obtain the IP address. primary router → wireless → from router WDS bridge mode or WISP mode is similar to this situation. Recommended

3, if the main router lan port → wired → from the router's LAN port, then from the router must turn off the DHCP function, this time from the router equivalent to the switch, from the router under the computer is connected to the LAN port from the router, the next hanging computer from the main router to obtain an IP address. primary router → wireless → from router WDS repeater mode, Client+ap mode is similar to this condition.

It is not recommended to be in the same network segment from the router as the primary router, For example, the primary router entry address 192.168.1.1,DHCP address pool 192.168.1.100-150, from the router set to 192.168.1.2, open DHCP,DHCP address pool 192.168.1.200-250, there may be conflicts, the following conditions:

1, if the main router lan port → wired → from the router WAN port, will result from the router WAN port and LAN port IP same network segment, unable to surf the internet. primary router → wireless → from router WDS bridge mode or WISP mode is similar to this situation.

2, if the main router lan port → wired → from the LAN port of the router, if the IP address from the router assigned to the primary router or from the router hangs the computer, will cause a gateway error, resulting in the inability to surf the internet. primary router → wireless → from router WDS repeater mode, Client+ap mode, because of the distance, the reason for the signal, from the router DHCP to the main router to hang computers under the allocation of IP is less.

In short, the router cascade if you want to turn on DHCP, you must from the upper LAN port to the subordinate WAN port, the computer is recommended in this way;

If you want to turn off DHCP, you must go from the upper LAN port to the subordinate LAN port, recommended this way when the computer is low.
